SPECIFICATION.

We, EDWARD DAvrEs and J AMES GERRARD, both of Liverpool, in the countyr of Lanca-ster, Kingdom of Great Britain and Ireland, have invented certain Improvements in Machinery or Apparatus to be employed for Dressing Flour, known as the Silk Bolter,77 for which Letters Patent of the Kingdom of Great Brit- The improvements consist of devices, too fully described hereafter to Vneed preliminary explanation, Vwhereby the apparatus is rendered more eicient in its operation.

In order that the invention may be better understood and explained in detail, I have hereunto attached a sheet of drawing, made upon a scale of about one and a half inch to the foot, similar letters ot' reference being marked upon corresponding parts on all the gures alike.

Figure l represents a longitudinal section of the improved silk bolter, the cylinder of which is made up in frames. Fig. 2 represents a halfsection of the cylinder, the thick line4 showing the line of silk placed according to the improved construction; and' Fig. 3 represents a detached section of one of the longitudinal rails, to the inner surface ot' which a flat blade or strip of metal, wood, or other suitable material is placed.

In these figures, a a is the cylinder, in which the flour is placed to be dressed. Between the silks iiush or ona level with the inside ofy the longitudinal ribs or rails are employed. In this View e represents a transverse section of one of the'longitudinal ribs or rails, to which is hinged or otherwise secured the swivel blade or strip, j', which is actuated from the outside ofthe cylinder so as to assume any position between the points e1 e2, the position of which being so adjusted that any amount ot' lift required to be given to the material being dressed may be obtained according to the inclination of such blade.

Having now described the method and arrangement of parts composing our arrangement of improved "silk bolter,77 and the practical manner in which we carry out the same, we would have it distinctly understood, in conclusion, that weclaim- 1. A reel, consisting oflongitudinal strips b b secured to disks or end frames, and detachable and adjustable frames c c, having the bolting-cloth flush with their inner edges, as set forth.

2. The combination, with the frame-rails, of

adjustable blades j', substantially as'and for` the purpose describedy EDWARD,v DAVIES. JAMES GERHARD.
